I've heard that it can be quite a pain to machine 6063, so watch out for that. I know that some tubing sizes are really hard to get in 6061, but, well, watch out.
If you can't dependably do press fits, then design around it. Make sure that all bearings are retained from both sides by either their flanges or snap rings/shaft collars. All the press fit is doing in this case is making sure the bearings don't fall out.
