I don't know how you are planning to do it.  It would be my guess that
it is hard to do in a manner that will behave sensibly when you put that
sort of construct into quoted music.  It is probably already hard to do
when using \magnifyMusic in multiple parallel contexts since you need to
store the information somewhere.

Perhaps most feasible is to just use \applyContext for increasing
fontSize by the given amount, and then use it again at the end for
decreasing by the same amount.  If someone _sets_ fontSize in the middle
then: tough.  But at least you do not need to store the old value
anywhere then.
