Yes, separate catch can't.
But you can 'exe'cute the whole try...endtry block -- as a workaround for you:
exe "try | echo nosuchvar | catch // | echo 'Caught' | endtry"
There in such a construct, you can use variable in place of catch regex.
Regarding your pursuit of the modification of catch -- my opinion is
that vimscript would gain if it had general mechanism to
substitute vars and expressions in any part of command.
Like $VAR workd in shell or [...] in tcl or Ctrl-R= in vim's own
commandline mode.
Such extension would cover any command not only catch.
Maybe existing {...} can be extended to expand in any part of the
command and contain any expression ?
At the very least, Ctrl-R= could be made to work for script lines, too.
