I/We might want to...

Consider these sentences, please:

a) I might want to see how he is in L.A., where it's warm.

b) I might want to spend more time in the room.

c) On the Wednesdays and Fridays of Lent, we might want to try to fast more intentionally.

My questions are:

1) What does "I/We might want to" mean in the above sentences? Does it bear a similar meaning to the fixed expression "You might want to", used to give suggestions?

Can I paraphrase "I/We might want to" with "maybe I/We will want to(but I/We cannot be certain)"?

2) Can I replace "I/We might want to" with "I/We might need to" in the above examples?
