In this sentence, what are the subtle differences
between「良さそうな(もの)」and「よい（もの）」? Would replacing with「よい（もの）」be grammatically
correct and sound natural?

良さそう usage in this context:【誰かが手伝ってくれたら、せめて「ありがとう」ぐらいは言ったって良さそうなものだったのに。】
（Vしても/したって）[よさそうなものだ](https://eow.alc.co.jp/search?q=%EF%BD%9E%E3%81%97%E3%81%A6%E3%82%82%E3%82%88%E3%81%95%E3%81%9D%E3%81%86%E3%81%AA%E3%82%82%E3%81%AE%E3%81%A0)
is a set expression meaning _could_ , implying the speaker's complaint.

Regarding replacement by 良い, 良いものだったのに is grammatical but sounds unnatural. It
is possible to use 良い in the form 良いものだが (or 良いだろうに). I don't feel difference
in meaning (良さそうなものだったのに vs 良いものだが), but 良さそうなものだったのに sounds gender neutral or
possibly feminine and 良いものだが sounds masculine.
