I'm not sure if I understand you. Is it that you don't want to
rack your wireless? Or do you want to rack it?
If so, you could easily just switch the "racked" unit into whatever
amp rack you're going to use ahead of time. Something like this:

You get the idea. I don't know if that's what you're looking for.
I just thought that if you wanted to use a rack for your wireless,
you could put it in one of these type of accessories, and switch
it over to whatever rack you're using for your amp for that gig.
Good luck to ya!
