put it in a big pot or in the ground, grow the leader out, cut heal repeat, develop bones, select branches -years here...annual cuts = healthy plant (no refinement techniques aside from core branch movements)
trees in a bonsai pot can slow to watching stone weather. my comments are for making branches and growing cut trunks forced into new leading trunks.
sure, tree trunks will grow bigger to some degree with time and any methodology, get a trunk size you want now and grow the branches; otherwise, reduce them over time without compromising the health of the plant...or grow a sapling
