The title says it all. Would this be possible in theory?
All options considered. Including HW upgrades (V9958, more ram, etc).
Pure a curiousity thingy.

Yes, but not a large area. 
Dynamic tile regeneration in tile mode (screen 1, 2, 4) is probably the best option and is limited to simple structures, see Space Manbow level 1.
Yes, only that the second layer can be updated with a very slow framerate wrt the main layer.
The simplest thing is to update it at 1/16 of the speed of the main layer
(I assume you mean horizontal scrolling, otherwhise the answer is: yes, all depends on the size of the scrolling area and on thr speed of the VDP copy)
I should have somewhere a totalparody version with parallax, where the clouds in the lego level move slowly in 8 directions according to the direction of the main screlling.
the main layer was scrolling at 1 pixel per frame in 8 directions
the cloud layer was scrolling at 15/16 pixels per frame in 8 directions
I'll share it if I find it
Ever played games like Ys-3?
Yes, it's perfectly possible, even in screen 5.

LOL! :RNFF:
Ys3 isn't smooth though, and it uses repetitive tiles to avoid rebuilding the whole screen (it skips what's already there). I assume Daemos refers to smooth scrolling.
I recall some ball game (challenge?) with a very open first layer. With v9958 it's possible to scroll smoothly with hardware... so the background can be scrolled with HW (acceleration
) and the foreground can be copied on top. If you get 20/25 fps some will consider it still smooth.
All options considered.v9990
well thats kinda overkill 4 V9990 2 V9958. It counts a little bit 
I indeed refer to smooth scrolling. Choppy scrolls do not count.
Ball quest is amazing. Thats indeed what I am talking about. So it is very well possible to lets say use two scrolling layers and scroll the backround at a minimal rate and still get just enough FPS to make a game playable.
So is this done codewise in theory? Can we use the HW scroll on foreground as well or do you have to use copy for at least one layer. If you scroll the visible page the layer on top would scroll as well so whats the clever trick done in this matter?
With hardware upgrades everything is possible but will it still be a MSX, that's the question i'm asking myself lately ?
If i wanted i could add a hell lot of nice hardware to an msx or even build an complete new system, but when isn't it a msx anymore ?
And if you overdo it you will fall into a deep gap between something like a super msx and for example a bad ps3 like machine 
Just one thought, should a new msx be capable of handling 3D graphics or should it stick to 2D instead ?
