They look pretty weird naked IMO, the front forks are raked out a bit much and look kinda off. You could put the engine in an old frame and make a bobber or cafe but it's just not gonna look right with the 250 frame.
You might be able to make a decent looking streetfighter but I still think it will look slightly off.
You're over thinking it, or under, I'm not sure. The ugliest part of a Ninja 250 (besides the pre-'07 body work) is the rear subframe. With minor work you can cut off the old subframe, and weld on tabs to mount any subframe, or build your own. It's only as structural as your bum.
sorry for the large pic, I'm just pulling pics off another forum, but as you can see it's got that nasty bar that hangs too low for a clean street fighter line.
super-moto inspired
that one is a little sketchy because there is no triangulation at all, he just cut them out. You can adapt 'modern' subframes to the bike very easily, since most bolt to the rest of the chassis (hence 'subframe' though on the ex250 it really is just the frame).
Here's a Honda CBR600RR subframe

not only cheap, but it will bolt on by cutting the stocker off and adding a few tabs. The seat & rear plastics bolt onto this, so it makes for a relatively easy upgrade for the back half.
And just 'cause I found this pic recently, my first 'sport bike'
It was an '88, the first year of the common ex250. I did the 'easy' mods. Flushmount signals, integrated turn signals, hacked rear fender, made an aluminum chain guard, used some aircraft stripper to 'polish' the wheel lips, and repainted a few bits. I regret selling that bike, but I had to buy books.
