A lot of complexity of JWST is driven by the very restrictive mass and size limits. If you get a wider rocket and a 50% larger mass budget, then you can skip a lot of the complex unfolding and you can probably make a comparable diameter space telescope for literally 10 times less effort, cost and time.
