Yeah. If I were to try to do it, I’d probably wind up with “it took 6 points to raise the skill, that gives you a 5 point talent with a 1 point credit towards something else, or a 6 point credit on something more expensive.”

Fiddly, as such work-arounds tend to be.

Or alternatively, I’d revise the skill costs to just be tiered in 5 point increments too.
