Hazel may need to do more than jelly shots of Kei's launcher grip to get it legalised, but it works.
SHORT VERSION: Uriel 2's Tip part fits snugly into the bottom of Wolborg 2's Casings. This can then be used in any base wolborg 2's sg will fit into, though Customise Grip Base would scrape, Burning Kerberous' Base is an excellent option (as the SG is quite tall, you want SP). It is just as fast and though it is not held in from falling out by anything but how perfectly it fits in and the friction of it's rubber, it is very stable, it's as though the two were made for each other.
Also, it's not dissimilar to removing Dragoon V2's tip to place a different SG in, so that's another plus on the "legalize it" side. And while it's only held in by (albeit very significant) friction, dranzer v's base lower section is only held in by a Magnetic SG so it's really the same thing, considering using a non-magnetic sg with that is legal (for example, I have a MWC from a draciel v2 that can hold it in place with friction), and Uriels tip is somewhat similar.
NOW IMMA GET ALL LONGWINDED LIKE THE MF LLD BD145LRF THREAD! But I'm literally shaking while typing so it's gonna be a bit rushed!
So, I thought more on the idea of the Draciel F thing, and also maybe a little about the wolborg 2/burning kerberous thing. We approached this the wrong way. Do remember, the tip of Uriel 2's defense mode connects to the SG anyway, so I'm totally calling it "A LEGITIMATE SHAFT PART AND CERTAINLY NOT A BASE TIP".
Anyway, you're about to love the whole wolborg 2's casings being different to wolborg 1's.
For starters, the rim of uriels tip is a bit too large to fit into any casings normally, it would but yeah, slightly too large.
However, wolborg 2's sg has a separate compartment at the bottom that is LARGER! And it just so happens it's the perfect size to stick the tip section in from the bottom!
It's not perfectly held in place, but then, neither is uriels tip TBH, and it can stay in for launching (haven't tested it in battle yet for a reason I'mma explain).
Now, there's still one issue, the only part that will work is Wolborg 2's casings, and let's be honest, with the height of those casings, you're gonna want SP's. BUT, sadly, the casings aren't tall enough for customise grip base, and if you try to do this setup with it, all you'll get is the sides of customise grip scraping the stadium on even the most gentle of inclines. My heart fell upon realising this, but I soldiered on, with a hearty "What the hell, worst case we can use wolborg 1/2's base or something.
However, my last ditch attempt succeeded, of course, Wolborg 2's shaft fits into Burning Kerberous' base! It's only the tip that causes issues there!
And guess what? It works here too!
So basically, get yer wolborg 2 casings and burning kerberous base and spare uriel 2 tip and GO SHOOOOOT! Just not at a tourney until we get it tested.
Possible q and a's:
Does it fall out: It's rubber, the casings seem to be made for it, it fits tight and like a glove, though it's not fixed in place and a worn down one theoretically could become loose, so it may not be a permanent solution, and as mentioned before, none of the bases hold the tip in themselves. That said, it easily survives a very strong launch. Haven't tested battles yet cos I am a little scared of breaking my burning kerberous base.
Is it legal?: Well, some crazy bs is legal in plastics, so it actually could be, though the committee will need to take the looser regulations on plastics into account when they decide this. YES KEI IMMA NAG YOU FOR WEEKS
Does it Kick carp: It moves like crazy, that's fer sure. I'm about to man up and try it out.
Basically: Wolborg 2's shaft, from the bottom, burning kerberous' base, or wolborg 1/2's base if you lack it.
On the downside, I can't test it against a grip defense combo because my parts are being used in this combo, eheheh. Oh, other downside you can't use an HMC like you can with Uriel 2's base, which is a shame. Uriel 2's base is better but this is a workable sub.
Update 2: Works in battle, like a beast.
God damn I hope this is legalised.
