I always thought of the Pentax 60-250mm f4 to actually be quite a brick... Longer than for instance the full frame Canon EF 70-200mm f4 L IS USM, especially longer at 250mm as it extends when zooming, weighing more than 1 kilo (1.2+ kg with tripod mount), that is not a small lens. In fact, that is in full frame EF 70-300mm f4-5.6 L IS USM territory (which is shorther)...
Of course, obviously a 250mm lens will always be smaller than a 500mm lens (not counting mirror lenses).
But doesn't the pro 40-150+1.4x fit this ?

"Considering the follwoing 3 mft lenses: oly 9-18, pany 12-32, pany 45-150"
IQ: just decent. Wide end, FF 18mm not wide enough. Tele end, FF 300mm not long enough.
So I don't find this combination is very attractive.
I'd argue it's "good enough" for most people.
Now, if you don't mind a larger setup (by quite a big margin), this combo is hard to beat:
- Pany 7-14 f4
- Pany 12-35 f2.8 (or even better: Oly 12-40 f2.8)
- Oly 40-150 f2.8 + 1.4x extender
This gives you high IQ from 14mm to 420mm (equivalent) at the cost of size and weight.
