Yes it’s do-able (I once split tender a Visa/MC GC purchase across 4 cards) but I had one store mgr claim that if any of the tender splits fail to authorize, there’d be no refund of the GC (I had enough cash on me to cover the entire purchase, if need be). None of the cards failed to authorize, so the split tender worked fine.
I’ve also done split tenders across 2 cards several times.
