Adaptors
For this situation it might be worth moving to a lightweight mirrorless system with cheap PK adaptors.
All the gear with no idea
There are lighter Pentax DSLRs with the the K-S1 being the lightest AFAIK or find a K-01 which is all of 3 grams heavier.

Now the question is. Is there an adaptor for the Pentax to Q cameras?
CHEERS Vic.
Yes there are third party ones available with aperture control and there is the Pentax Adapter Q to K which includes a mechanical shutter in addition to the usual aperture control.
From these the third party ones do a great job and don't cost too much. The genuine adapter costs a whole lot more and is more difficult to find. It also has a tripod foot which makes it more stable when mounted, and probably also protects the Q body a bit more.

I'll re-suggests the K-S1 as the lightest of the K mount cameras that does most of what a K3 can do. Nothing wrong with the Q either only K mount lenses with it are not wholly suitable.
Have you considered the MX-1 ? It's got the same size sensor as the Q, similar in use to the GR only with a reasonable quality moderate range zoom lens (as opposed to it being a compromised super zoom.)

The MX-1 is a good option too, again a bit tougher to find.
Have you tried the K-30 or K-50?

Lots of gear - but not a lot of idea!
There's a mint K-S1 on eBay for £205, 1800 shutter activations.
One decent looking one on Facebook for £135 in Shrewsbury.

As for the Q, having just aquired one myself I have to say lovely little camera, you don't even know you have it round your neck, pain in the ass seeing the LCD in bright light though. Can't wait for my cheapo third party adaptor to arrive so I can try my 50-135 DA* on it.
As for Q lenses, the 5-15mm seems readilly available but the 15-45 is like rocking horse dung, unless your prepared to order from Japan and stump up the import duty.

Despite my comments regarding the adapters, I completely agree with John's comment above and also recommend a smaller K body. The K-S1 is near unbeatable if you just want a small cheap body with great IQ. Unfortunately, quite a lot of people think the same so they can be a little tough to find.
The MX-1 is a good option too, again a bit tougher to find.
Have you tried the K-30 or K-50?
I have owned the K-S1 and K-30. K-S1 is very fragile/made of light thin plastic, but IQ wise is epic for the price. K-30 is much better constrution/weather sealed, but I wouldn't go near that again (with it's aperture failure issues) if you paid me, or accept the idea that one day it will be for manual aperture control lenses only.
Light 35mm lens on the K-S1 is an awesome bundle. Uncomfortable grip and tiny burst buffer, but fun for group shots with the flashing lights countdown counter.

This is just a thought for the future and not immediate.
