You'd indicated earlier that you had some flexibility in names:

If so, then maybe this solution is adequate:

$ cat file
typedef hnd<X_Y> X_Y;
bool is_a_Z(const X_Y& inst) { return inst.isA<Z>(); }

$ cat cvt.awk
BEGIN{FS=OFS=""}
{
p = ""
for (i=1;i<=NF;i++) {
if (p == "_")
$i = toupper($i)
p = $i
if ($i == "_")
$i = ""
}
}
1

$ awk -f cvt.awk file
typedef hnd<XY> XY;
bool isAZ(const XY& inst) { return inst.isA<Z>(); }

If not, it'd require a little different approach...
