That would be very confusing. I'd expect "outer" and "inner" ways to  
be the same kind of way (closed). Several "outer_part" ways instead  
of one "outer" would be better, but that's still not good: What if an  
inner way is also so long you'd like to split it up?

Basically, I think using several open "outer" ways like this is  
abusing the fact that there's just one outer way to start with.
