Juniper Question

I know not a lot of readers read this blog if there aren't chapter notes to go over...okay so I know not a lot of readers read it then either, but I'm going to ask it here first and see if I get any early response. I'll mention it next time I update Juniper as well.
Basically, my original frame for Juniper included a rather small cross over. It isn't really connected to the main plot but it would drift in and out for a while (no it's not Harry Potter, though that might be really fun to play with some day).
Without revealing too much right now, I'd just like to sound out how readers feel about cross overs in general.
The first chapter that would include the cross over is 'approaching' - really, really slowly, but still approaching. And I'd just like to start feeling out whether or not I should take it off the board.
I'll probably give more details later if I'm still undecided, but any opinions now would help.
