Sorry, but I probably wouldn't, for a couple of reasons. First of all, a regular stroller is not designed for shock absorption. The wheels are probably hard plastic, so combine that with no shocks, and you're talking about a lot of impact translating up the stroller. That's a lot of bouncing around. 6 weeks old is kind of borderline (depends on who you talk to/what you're comfortable with) to be in a jogging stroller, anyway, so I *definitely* wouldn't put a little one that young in a non-jogging stroller that's going to have that much jostling around.
Then, in addition, by trying to run with a regular stroller, you're going to put a LOT of wear and tear on that stroller. Travel system strollers especially are not really known for being durable, so chances that the stroller will hold up for long under that kind of use are not great.
If it's a question of money, try checking craigslist or even freecycle for a jogging stroller. I've heard of lots of mamas getting great deals that way. Or even garage sales!
