I don't beleive you can do this.... or at least you don't want to.
The old (3.2.3) toolchain had built into it descriptions of different
processors which mad it difficult to add new processors.
The newer toolchain starting with 4.5.3 exported this to msp430mcu because
it is much easier to maintain.
But this also means that it is very difficult (not impossible) to add new
processors to the older toolchain.
The other problem is the fr5739 is in the x5 family (cpuxv2) which the
older 3.2.3 toolchain doesn't support while the 1611 is an x1 and 1st gen
msp430.

Can't say I understand where that is coming from. Why do you believe that
it is hard to move from one toolchain to a later version?

Depends on how much of your firmware knows about the 1611. But that is a
cpu thing rather than a toolchain thing. but there is some overlap with
the toolchain.

nope. not in my opinion. I think you should byte the bullet and
1st get your current firmware working on the 1611 using the 4.6.3 toolchain.
2nd port to the new cpu.
