It's a good point about converting characters. That said, d20 Modern's character classes are pretty generic, so most of the flavor of our characters is not contained in the mechanical structure of them I feel like. Like, the ability to use her Int bonus in an attack, or make a wacky plan that gives allies some bonuses is really in-flavor for Death Otter, but they're not things that I was thinking of in connection with her before I started looking at d20 Modern. All I knew going in was that I'd want the Intelligence focused class. From there I looked for the options that seemed to suit her best.
I could simply repeat the process with 5e and come up with another Death Otter that, while different from this one in terms of rules, is equally valid a translation of my mental template.
The only stumbling block I'd have is that I don't see Otter starting out as a wizard, which means I'd have to multiclass, which has some consequences in terms of game mechanics. But I'd be willing to do it anyway, I think.
