Hi Pierre
This sounds like a question for the PROJ mailing list [0]. The transverse
Mercator already
exists in a very accurate version in PROJ but if yours is both faster and
better it is worth
considering.

Subject: [OSGeo-Discuss] Attn: PROJ: Transverse and oblique Mercator
Jody Garnett posted on the incubator list some CONTRIBUTING files, one of which
is at PROJ, so I've been looking around. I've written code that computes the
transverse Mercator projection accurate to within 1 mm over 80% of the earth
and 100 µm over 71%, that is, within 100 µm up to 45° from the central
meridian. Are you interested?
I'd also like to understand the oblique Mercator well enough to write code for
it and what the differences are (besides the obvious) between Alaska and
Switzerland.
Pierre
