78 GS750 - 93 Katana Mash Up

I've got a 78 GS750 EC and I found a 93 Katana 750 on the local craigslist last night (link below) that is non-running but complete. I thought this Katana would be a good candidate for swapping the front-end and swingarm onto my GS. Can anyone who's done this chime in with verification that this is a good idea? My reasoning is 15 year newer brake/suspension technology as well as clip-on bars, weight savings, etc. Any help is greatly appreciated. Thank you.

You need to get a 30 x 48mm bearing for the bottom of the front triple clamps, otherwise it's a bolt on front end swap (that's a fairly common bearing size, so no big deal).

I don't think you can get the Katana rear wheel into the 750 swingarm, so you will either need to use the Katana swingarm and weld some shock mounts to it, or use the alloy 1100 twin shock swingarm. Not sure if the pivot bearings / bolt size are the same across the three, so you might have to sleeve the 750 pivot bolt.
 
Well, if you do pick it up, I'd like to buy some bits and pieces from it. I'm doing a katana / GS650 mash up.
 
Thanks for the replies so far. I haven't been able to procure the Kat yet but the more I read about this swap, the more questions I have. From what I've read, the Kat front end is significantly shorter. How big of a concern is this? Also, since (I believe?) the Kat is much lighter than the GS, will the forks be too soft to support me? I'm 5'10" and 190#. I'll tell you one thing, I picked the wrong time of the year to be doing this... Sunny and 70's for the next week...

I was thinking the Kat swingarm was a direct replacement in regards to the pivot/bolt measurements but I hadn't thought about shock mounts... Not much for welding aluminum... Anyone convert a GS to monoshock setup???
