If you're willing to put up with the extra work, that might be fun. One would be gritty and serious, whilst the other would be completely off its meds. XD I'd honestly be fine with either really (as long as the dark one isn't dark to a stupid extent, but I'm sure that won't happen), but yeah.

And hey, if they both work out we could always have a crossover at some point, but that's probably getting way ahead of ourselves.
