Economic Potential of Greater Brittania?

Though it may be ASB to try to divert the ARW away, what would you say, in the case that the UK had kept royal control over the American colonies as well as expanded into Australia and India, would be the full economic potential of this expanded empire?

Would Britain even be able to logistically expand into Asia while they held the American colonies?
 
Yes, absolutely. Expansion in the East was done by John Company and self funded by revenues generated by Bengal tax collection. There's no reason that would change. If anything, Britain would gain more money as cotton plantations generated huge profits.
