You can only maintain the benefits of HG as long as you maintain the intended relationships between cogs, so if you had a 28-25-22-19-17-15-13 and a 32-28-24-20-17-14-12 and you wanted to make a 32-28-24-20-17-15-13, shifting would suck between 20-17 or 17-15, depending which 17 you used. Merging HG cassettes only works when there's three consecutive cogs of the same size between them.
IMO you should quit futzing around with freewheels and rebuild the rear with a freehub; there are bound to be more options that way. Prolly get away with the same spokes.
Well, I don't follow quite WHY you say that about the relationships. I've read about folks customizing HG cassettes to suit their needs. But, indeed I don't know much about it and, indeed, I am asking about a freewheel and not a cassette.. I'll simply have do more research and look at the differences on cogs.
I do know freehubs are a much better way to go, but I'd have to rebuild the rear wheel and I don't have a truing stand. It'd cost more for me to either buy the stand or take it to the shop and have them rebuild the wheel. I have the hub to do such a thing, and the spokes wouldn't be but about $35 for a set of basic stainless, but add it all together and I just figured building a HG freewheel might come out cheaper and get me where I wanted for now. Hmmm....
