Nope. But there's a way to ease the transition.
Once you think of the Q gear as an integrated SYSTEM and customize it to suit your needs it makes good sense. Also consider how much time and accommodation you've put into the DSLR's and allocate the same to the Q to feel comfortable and competent with it.
IME, the Q7 sensor 'upgrade' is significant if abandoning the APS-C format and the investment in the 08 lens made a big difference for me. I can comfortably travel with the Q7, 03, 06 and 08 lenses, three batteries and +4 & +10 close-up filters and not feel I'm missing anything today. It helped to begin to rely more on AF too. If only it had a .9 meg LCD screen...but battery life would take a big hit.
Also consider a smaller notebook or tablet for PP-ing and fun pix display as an integral part of a compact travel kit. My Q7-kit has about one fourth the size, weight and energy footprint as the APS-C equivalent gear.
