got a plumbing question for the experts,

currently, this is the plumbing i have in upstairs bathroom:

|
|
\________________|__________________
up for toilet vent to attic to roof drain down

i would like to move the drain for toilet (move the toilet) more to the left
(on the schematics) this invoves bringing the horizontal drain up by about
8" to cross a structural beam (the part after the vent). Is is acceptable
to do this for toilet drain? It would be 2-45° elbows back to back (i don't
see problem with this, as long as the overall slope is maintained).
If this is done, does the vent have to be relocated - ie would it have to
come up from the new elevated section , or can it remain as it is?
the new plumbing would look like this

I would rather see the vent moved but, as a practical
matter it may not make much difference.

Should be no problem, I did that in the original plumbing in my house
many years ago and have had no problem.

There is a code requirement that the main stack (vent for toilet) must be
within 3 feet (I think) of the toliet flange.

As long as the overall path to the vent is up I don't think you will have
any problems. I have seen a lot of strange things work just fine.
