i was also pondering reversing the order.  rather than being a suffix
that gets mucked up in syntax, add a pass through.  but that too can
get ugly.

pipe <command to pipe into> <normal command> <command args>
(gdb) pipe "vim -" thread apply all bt

when i thought of a secondary command, i think half the power of what
Abhijit proposes is having it in a single command.  especially when
shell scripting is all about slightly tweaking the command and looking
at the result.  that way you dont keep flipping between the two -- one
to update the command to pipe into, and two to update the stuff you're
piping out.
