Ello GB,
One major problem would be if you were involved in an accident, be it your fault or not, the insurance companys will go to extreme lengths to not have to pay out a claim.
Since you have a resticted license i would imagine a major concern, for an insurer, when considering a claim would be that you were using your bike, legally, in accordance with your resticted license.
Wait for the bike to be resricted and then you are legit,and when you first go out n about you'll be smiling twice as much.
The time, effort and cost of obtaining your license should tell you to do it the legal way.
