Regarding the syntax, the mp=unsharp filter supports a format of the
kind:
[lc]XxY:AMOUNT

while unsharp supports only (awkward) positional parameters.

A better mixed solution would be to implement a syntax of the kind:
[lc]=XxY+AMOUNT

for example:
l=5x5+0.3:c=3x3-2.0

while back-supporting the old syntax.
