Hawk, the cost of visit visa is quite small (I think £78) which makes the risks involved quite small.
It's difficult to predict how the application would be viewed.
Just go ahead and do it.
One thing though Hawk, I suggest you go for Family Visit Visa
The UKBA webpage specifically for this is Can you come to the UK as a family visitor?
If you need additional information on applying then please review the information I just posted here on this thread
Good luck and let us know how it works out.
