I tried a similar combo since I don't have Gaia Dragoon V base anymore =/. I used:
AR:Flash Leopard
WD: 10 wide
SG: Right SG
BB: SG Flat
(I'll call it f.l.)
Versus
AR: Bistool
WD: 10 Heavy
BB: Draciel MBD w/ four Metal balls
(I'll call it compact)
and then Versus
Driger S with 10 Heavy and a right MG core(I'll call it driger).
RESULTS:
Battle 1: Compact wins:KO
Battle 2: Compact wins
utspin
Battle 3: Compact wins

Battle 4: Compact wins

Battle 5: Compact wins:KO
Battle 6: Compact wins:KO

In every battle I launched F.L. second and used banking with it. All battles were performed in the Attack Stadium(original takara) using short winders.
I don't think Gaia Dragoon V's BB will help it perform too much better.
