Mix hairpin and ho alt?

[ehall8702]

I have a 180ho alt I wanna keep in factory spot and have access to a 350 hairpin (6 phase, yeah I know it's technically 3 phase but ease of explaining to sum warrants calling it 6phase ). Hairpin won't fit in stockk location and will fab a bracket where my ac compressor sits now. Before I get a ration of shit, yes I know they make dual brackets and LL that but ac don't work and don't need it up here but a day out if the year so out it goes. But main question is can I mix the two feeding my dual batteries without issues or do I need some kind of regulator or controller? Kinda figured the HP would supply most at idle and the HO supply more at highway speeds, kind of complimenting each other. Since they are on opposite sides of truck and so r batteries, figured I'd run one alt to each battery to save wire, and since both batteries r connected anyways would be same as both alts to one battery .
