Yes, you can do that.
Just make sure the R2-R4 link can handle traffic for:
o R2-to-R4.
o R2-to-R5.
o R2-to-R3 (backup path).
o R2-to-R1 (backup path).
Ignore the backup paths if you're going to build strict
paths for the MPLS-TE LSP's (recommended), as the LSP
wouldn't form across them anyway.
We do this within our core network to support load balancing
for non-equal-cost distances (towards peers or customers),
even though bandwidth within the core is the same; just like
your case.
Cheers,
Mark.
