Envato improvements - licenses

Hi. Recently encountered some issues where buyers continue use item with single use license. 2 cases known, probably more unknown. I understand maybe he or she do not want waste time for purchasing another license or just do not see that there is available other licenses because of drop-down menu on purchase page. Probably not much people clicking on that menu. Replacing drop-down menu by checkbox with all licenses visible with price. Depending which license currently checked, corresponding description appeared. Price for selected license also might appear, depending which checkbox is selected. This might bring more sales to “upgraded” licenses. What do you think?
I quickly made an example, this will look like this:

I think it would make more sense to have it as an option on the payment screen. Because many users buy by comparing the base price before purchasing.
