[Eshen]

Here is my XI for the first two matches:

Tamim
Liton
Soumya
Mushfiq
Shakib
Riyad
Saifuddin
Mash
Miraz
Nayeem
Fizz

I would go with a spin heavy attack against both Windies and Ireland, unless the pitch is damp (that case Rahi gets Nayeem's place).

Given how long Shakib has been out of match practice, I would keep him in middle order for first two matches. Perhaps he can be promoted to #3 in later matches, at expense of Soumya or Liton.

For last two matches:

Tamim
Soumya/Liton (whoever does better in first two matches)
Shakib
Mushfiq
Mosaddek
Riyad/Yasir
Mithun/Sabbir
Saifuddin
Mash
Miraz/Nayeem
Rubel/Rahi

I am all for giving Mosaddek a go for couple of matches this series, at expense of a regular offie. But it's pointless to take him as a late order batsman given his lack of power hitting. He should be taken in the XI only if he can be accommodated in middle order.
