I feel that i don't have the information i would need to answer your questions. So i would like more information before i answer:
- Would additional stretch goals delay the release of the game?
- What are the trade-offs involved with adding new stretch goals? Would there be less time/money e.g. for polish or reactivity?
- Would the improvements be available in the base game or only via expension or DLC?
Besides of that the intuitive answer is of course that more quality content is always better
Though to be honest i would probably not be willing to spend any more money towards this right now. But i guess other would just do that so i might just profit from that ^^
