Nope. Triplizers don't come in 50t, I think 45t is the largest. And they all seem to use a 74mm inner circle. Not even TA makes a 74mm larger than 32t. http://vintage-trek.com/tripleizer.htm

I'm sure Highpath could make what you need. Won any lotteries lately? (If they're still in business, I haven't been able to get to their website in quite a while.)

Sounds good if the price is right and you can find replacement 36t rings in the right BCD
