It just depends on how 'snobbish and precious' you want to be about your rockery, Hank. Personally, I wouldn't in my own garden (purely personal choice) but but I would imagine that a mix could look quite good and colourful.

You aren't going to have a lot of room with all the other plants you've got. What you could do is put the prims in for now and then when they have finished flowering dig then up and line them out at one end of the veg plot for the summer.

Sorted, thanks, in they go and I'll do as you suggested Sue. They'll certainly brighten the area up.
