Be very careful in saying that if your IP knew you had more money than paying back your debt or shares then they will have it!!!!! I got a bonus one xmas and when I had my revue I had to pay it all back. Free of Debt. Good luck.
Nothing to stop you buying the shares with your own money to which the IP is not entitled, but any income received by way of dividends would have to be declared as income, and any gain on the sale would form a windfall.
