It's a terrible idea. The End.
P.S. Cornering and climbing will be so different than what you are used to, that you will soon realize the person trying to sell that frame to you as a road bike is an idiot, and doesn't give a rat's *** about you. The wheel base is shorter, the bb is farther back (hence, so will your feet be farther back), and the placement of the bars (given the same stem length as your last bike) will be uncomfortably far back. There are also many other proven facts regarding "trail" and fork-rake issues that would make it hard handle in a responsible fashion for the street, and your body.
The best idea is to get a frame similar to the one you already had, so you can continue to ride as you are used to. Or using this as a chance to make any adjustments that makes sense.
