LB- thanks! It’s nice to know that somebody actually reads my long posts!
In terms of the changing nature thing, I would think that if it is a result of your davening, it would be fine. Because then, it is not coming from nowhere – it is coming from the fact that you raised your level by davening so now you deserve more than you did before. You never lose out by davening (except if you daven to marry a specific person, and maybe there are other examples like that, but most of the time, you don’t lose out by davening).
