I have done it a few times. It will sound great in the front (assuming your bass sounds good through it in the first place and the soundman knows his stuff) since the DI is quite honest, and the preamp can give you a far more lively sound than most clean DI boxes. However, if there isn't sufficient bass-friendly monitoring you will be in trouble.
Pretty much any beat up old bass amp available will do better in the low frequencies than a lot of monitors. Depending on where you are playing and who you know in the area you should consider what you could borrow. Just set the thing flat, feed it the TH signal and feel a bit safer.
