I think there's also another problem with at least two of the spinn-offs and that is tone.

Fairy Tail is mainly a shounen series, but Blue Mistral and Fairy Girls are Shoujo genre. They'd need to quite heavily adjust the style of those two so they fit in with the rest of the story and not stand out like a sore thumb.

But if they can pull that off and find a way to integrate them into the main timeline well, I'm all for it. I'm far from a fan of doing filler arcs that contradict the rest of the series or where they never say when those stories happened and wave it away by "some time before" or "at an unspecified moment earlier"... so in other words don't do it like Bleach.

Ice Trail, being a prequel and with a well established position in the timeline, of course doesn't have that problem, but on the other hand I didn't really like it, so meh...
