If I roll all of them either I am going to end up earning segregated rewards (sats, RP, lott tickers, GT etc) but do you guys think it is worth an investment like that?
It appears that you've already done the necessary calculations, so you should be able to make an informed decision about what will help you achieve your goal. Just keep in mind that exchanging 4500 RPs for only 60-70 WOF spins may not be a good value, as you may end up losing sats in the process.
