Dolgo is considered a semi-dwarfing stock. I believe grafting a crabapple tree onto a standard apple rootstock will produce a larger, but not full-sized tree. I haven't found any sources from people who have done it, but logically, evening out the characteristics (the smaller growth habit of the crab, and the bigger supply from the standard apple, which has the potential to give more energy than the crab can utilize, especially under ideal conditions), the tree will be sturdy, bigger, but not standard size.
Crabapples are usually more disease resistant and poor condition tolerant than standard apples, which is why standard apples are often grafted onto crab apple rootstocks. Reverse this, and I'd expect reversed performance as well, in these regards.
Also, standard apples are often healthy seedlings, but seedlings will be slightly variable in all respects, because of genetics. If you want to go higher quality, you can clone a disease resistant and vigorous tree for use as a rootstock, by mound layering. You basically cut the original stem down (coppice), and then when the new shoots are a suitable height, mound soil up around the, to promote new root growth. The process is summed up in the picture:
