[consulting] advice needed: slideshow with pagers on separate blocks or overlapping theme regions done "right" way

[Audrius Naslenas]

Hi,

Have  a  task with showcase type site, which is basically
custom  styled slideshow gallery (view of nodes full of pictures).
The problem  is  that I have 2 galeries on one page, one of them,
on the right has  pager  on the right side, the left one - on the left.
The idea is  to   have   only   one  of  them  active: if active
"right" one - main content content of this  gallery  covers  (z  index)
the content of the "left" one, and vice  versa.

Image  is  attached. Green are pager pictures from "left" galery, red
ones  -  from  "right",  center  area shows on top content from galery
which is now active with MouseHover action.

Looking currently at two solutions:
1)  Finding  slideshow/rotator type module, which can display as
main content views  fields  or  full nodes from views  and  can  have
pager made from  thumbnails  in  separate  block, which activates
main content depending on which pager is MouseHoverbut  have no luck
finding such module.
2) Adapting theme, which is more or less customisable to have
overlapping regions without needing to build from 0.

Which of these ideas is may be done with least headache on D7?
Do  not  want  to  use  older  cores,  it is more or less ok
 if  the  problem  is  solved  by porting old theme. If so - which one
 would you recomend? Maybe some other solution?

Thank you in advance.

p.s.  It  is client idea to have 2 pagers on one site, so it has to be
done this way.
