Au contraire, Mon Frere!

The pipe die will do a great job as the pitch is the same. Just don't
screw it on too far. It's actually very difficult to get a straight die
of such large diameter and fine pitch to engage accurately enough to
repair the described thread damage. With the tapered thread die, the
taper guides engagement. File the sawed ends accurately square for
easier threading, and debur.
