AMBER: mutation of Tyr to Leu with TI

Dear amber users/developers,

is it possible to "mutate" a Tyr to a Leu within one thermodynamic
integration simulation with sander?
My understanding is that this would involve the following:
o conversion of the OH in the Tyr sidechain and the carbon atom bound to
it to dummies,
o conversion of the CE carbons to hydrogens (HC) and of the H's bound to
them to dummies,
o conversion of the CD bound H's from HA to HC,
o conversion of the CD carbon types from CA to CT,
AND
o letting a third hydrogen (HC) appear at each of the CD carbons.

How can I achieve especially the last step?

Thanks very much in advance,
Oliver
