The 16-45, as much as I like it is, a little short and on K-7 started showing its corner weakness which was not apparent on my previous K100D.

My copy does have a bit of extreme corner weakness at some apertures/focal lengths, but no more than many lenses.

I definitely need a true wide-angle.

Buy a Sigma 10-20 or soon to be released 8-16mm, I would recommend the Pentax 12-24mm, but it might overlap too much with your 16-45mm.

The built-in flash is underpowered for fill-in purpose in daylight conditions.

Maybe, I guess I never use the built in flash.

I also thought about getting a compact body for my girlfriend since many a time we would "fight" over the camera ot get "that" shot.

Buy a second body? Not sure if you have looked at some of the new mirrorless systems or not. They are much more compact than any SLR.

Looking at possible options I came to this: Get a Nikon D40 (250-300$ 2nd hand) + Sigma 10-20 (450$ 2nd hand) and/or Nikkor 16-85VR (500$ 2nd h.) + SB-400 flashgun (130$) + Nikkor 35/1.8 (250$).

Lots of overlap between the Sigma and the Nikkor, and the Sigma is strongest towards 20mm, but sometimes overlap is good. Maybe consider the soon to be released Sigma 8-16mm, or get a wider range 18-200mm (I know this isn't as good overall as the 16-85mm though) or third party 18-250mm.

In my idea to get a Nikon these are the deciding factors:

Very good 16-85VR not quite matched by anything in Pentax lineup. Please see the cost comparison below.

True, but the 17-70 is about 1 f/stop larger aperture at 70mm. The 16-85mm is an excellent lens if you can tolerate small apertures. I could see it being an excellent lens in a place like Italy with a lot of light and nice scenic vistas.

Nikkor 30/1.8 - no Pentax equivalent. And finally D40 - beautifuly compact, quiet shutter, 1/500 (!) flash sync speed and my beloved 6MP sensor. Do you really need more for travel?

True, but one could argue there is no equivalent lens to the Pentax 31mm f/1.8 on Nikon.

I find people often come up with excuses to justify switching systems, rather than actually needing to switch. Heck, I have done it myself on numerous occasions. But the bottom line is you have to go with what fits your budget and your needs. I won't try to argue you stick to Pentax, but depending on your usage you might not find the grass any greener with Nikon (except if you shoot JPG).

My thought for a travel system would likely be a Sigma 10-20mm, Pentax 18-250mm, and a Sigma 30mm f/1.4 (or Pentax 31mm f/1.8). Or my personal setup right now is the Pentax 16-45mm f/4 and 60-250mm f/4, and Sigma 30mm f/1.4, Pentax A 50mm f/1.4, and Rokinon 85mm f/1.4.
