Does Getum við…? sound like Can we…? or Are we able to…? (politeness/nuance)

Usually it matches everyday English Can we…? and is neutral and natural.
If you want to sound more tentative/polite, you can use expressions like:

• Gætum við hittst á morgun? (could we…?, more tentative; from geta in a conditional-like form)
• Væri hægt að hittast á morgun? (would it be possible to meet tomorrow?, more formal)
