Is it dumb to invest in two separate wireless brands?

I want to get a few solid Lectro wires, but in the future I would like to also get a Wisy MCR54/MTP x4 system. I think it would be nice to be able to choose the best for the situation with smaller shoots, but when I actually need more than 4 wires at a time, would it be really terrible to be using two different systems? Would post even notice, with all the other variants usually present in large wire setups (variance in mic, rx, tx even are not usually all uniform across 7 talent per se).

Just wondering if my plan is bad. I think Lectros are extremely solid and time tested, and would like a core kit of them, but any further expansions I might want to go Wisycom. Terrible to mix the two? (obviously the tx/rx aren't intercompatible but I'm not looking for that)
