When you try to ram something down someone's throat they tend to resist. However, if you can provide something tasty and appealing they'll eat it themselves. Write a nice program, show it to your Perl programmer, and if they also think it's nice -- then you've already won.

I've had success in situations with tight deadlines: the only way I got it done quickly and without bugs is by using Haskell (as opposed to PHP). Another place where you might have success is by writing a small compiler or interpreter for an internal language. Start small (in a niche, if you will) and expand upon that.
