I'm pretty sure Igiss has seen your model Mohr. I imagine he gets a lot of half baked ideas and unfinished models so he may not voice an opinion on this until it gets closer to completion.
I like how well you've picked up the Kusari aestetic. And though I too see a pontoon speed boat in it, I will only offer a practical suggestion:
You indicated you want this to be a 'light' bomber which I assume means less armor/nanos and a bit more manueverability. That sounds like a logical idea for the Kusari, who typically have more manueverable/slimmer ships than the rest of the houses. I wonder if the size of this ship will make such a light bomber too big of a target though. If I go off of the size of the cockpit for scale, this bomber is already about the size of a Kusari Gunboat (only with smaller wings.) Making a light bomber with a large hit box will make this ship a very easy target. Perhaps shortening the 'pontoons' by about 50% would give it less of a target cross section and make it more appropriate to refer to it as a light bomber. Yes, this is a drastic clipping of its hull, but you should consider that this ship is also wider than a gunboat by virtue of its twin hull design, so some balancing compensation would be good.
Nebotuda can't wait to flight test this new piece of Imperial hardware!
