There indeed is... can't say re: the time/money ratio but it sounds like it could be neat. Maybe some Mexican herbal medicine would help make it go down easier.
Interestingly, Pino Suarez just reopened a few weeks ago after extensive renovations... the iconic pedestal is now restored to its former "glory," i.e. coated in a white, um, pre-Hispanic glaze. It actually looks pretty sweet, and there's a light show that they do on it... well, I dunno, I saw it the first day it opened, and there was a sign saying every day at 7 and 9 p.m., but now that sign has been artfully covered by a taped-on TV box or something and I haven't seen the light show since. It was a touching tribute to Ehécatl with rain and wind effects and trippy graphics. All of Pino plaza has actually been renovated, and it's sort of nice, but still a tad sketchy... the glue-sniffing colony with the huge couch is still in place, but it just features a lot better lighting.
