More trouble than it is worth? For a homebuilt aircraft sized moulding just (gently) use a plastic 'scraper' to spread the resin and fully impregnated, then vac bag. To roll out the resin would need a fair amount of experimentation to get the resin spread evenly and to fully impregnate the cloth. Reasonably straight forward to create a cored laminate with a wet layup and vac bag, probably the most cost effective method. It is labour intensive, but a roller system will be pretty expensive.
