I know I can say
- I would write a letter if I wanted my message to be warm and personal.
But is it grammatical to say
- I would write a letter if I would like to be warm and personal.
I'm confused because this is conditional statement so there should be no would after if (in general) but on the other hand I would like has different meaning than I like/liked.
I'd like to make sure if both sentences are correct.
