At this moment, there are three gmap*.img files on my device. Two that came with the device and that one osm based (most recent openfietsmap.nl full version) that I used all day today. You can switch on and off maps as you like, so I guess (have to try this out) that mulitple osm based maps should not be a problem as long as the Family-IDs and the filenames are different. If you want to, I can try this tomorrow and let you know. Anything special you want me to try?
You can have more than one Family-ID in one gmapsupp.img. I use this feature for contour line layers in my topo map: http://www.kleineisel.de/blogs/index.php/osmmap/ In my eTrex Legend HCx I can switch these layers on and off individually. Some of the newer devices can't do this AFAIK. Would be nice to know how the 30 behaves in this respect.
