Anyone put a 2 stage thrower on a Cub 149?

Ok this is the 3rd storm already this year where I had snow coming over my QA36 on a 149, and also, the narrow width means alot of passes. I have to ask the question if anyone has had luck installing a 2 stage unit. Rather than finding a QA42 inch (my father has one on his and it works well) I would rather consider a 2 stage like a 451? 551?. I know someone is going to say the 14hp won't be enough but realistically...the 2 stage has a high speed impellor throwing the snow and the slow speed auger feeding the snow. The QA36-42 must waste a lot of power churning that snow through the auger and throwing it. And even at that is works pretty darn good. Mine needs end bearings, guides, botting scraper, and I should go through the gearbox anyway. My main questions are;
1. Will any 2 stage models physically attach to the frame of a 149 (width, locking mechanism, and height?)
2. What drive pulley diameter was the closest fitting model meant to run with?
3. I like the idea of being a taller opening. I've had 6+ inches coming over the top already this year.
4. I don't think it will bog it down. If it does, I will just drive a little slower.

I do have machine shop/welding capability so at a minimum I'm expecting to have to move/alter the idler pulley locations. Lift arm is no problem I can make or modify one.

I need to get the drive speed right (somehow). I can maybe alter the pulley on the blower or I can make a pulley for the engine if I need to increase the blower speed. Alignment of the pulleys/belt will be a pain but I'm sure I can work it out. Anyone have any suggestions???
