Looking at other examples, I find the taller literati trees to be very interesting with blooms. Tall windswept also an idea that I find interesting for this guy...

Flowering quince, Chaenomeles, is related to the apple family, Malus. In nature Chaenomeles are almost always a shrub, almost never naturally remain single trunk. If you see an old single trunk Chaenomeles, you need to assume a human has actively intervened over the years to keep it single trunk. There is a 40 or more year old Chaenomeles 'Minerva' on our farm, it is a huge shrub, hundreds of branches coming from the ground, covers a patch 15 feet wide by about 3 feet in width. No single branch taller than 7 or 8 feet, no single branch larger than 1.5 inches in diameter.
Flowering quince are easily trained to many styles, including single trunk styles. Like junipers they are almost horticultural ''silly putty'' easily trained to most styles.
They can be trained in informal upright styles, much like a small apple tree. Flowers and fruits are the key attractive features of Chaenomeles, especially their habit of blooming off and on all year with peak bloom in spring, and a significant autumn bloom, especially if pruned in early summer.
A windswept tree, just looks odd with big double scarlet red flowers. I would avoid going windswept. Literati, informal upright, semi cascade, full cascade, clump and raft types styles are all good. Formal upright and windswept and any of the mainly for pines and conifers styles should probably be avoided.
