Ramadan: Should an Imam restrain his tears when leading prayers with jama'ah?

Assalam o Alaikum.

Those who have lead prayers, or those who lead prayers, and have a habit of crying with tears in salah,
should they lead prayers?

or is it preferable to ask someone else to take the duty of leading salah?

p.s. crying is out of khushoo
Update: @majeed:
i know that crying in salah is encouraged, but, does crying too much invalidate salah?
If I want to cry in salah, and 'brothers' invite me 'off' to prayers, would it be better to control my tears? or to 'cry' irrespective of the outcome?
