The donor is a 1/72 desktop 'Flybe BAe 146' with the rotodome from a Grumman E-2 Hawkeye and a pair of CFM turbofans.
The An-158 looks remarkably similar to the BAe 146 but has twin engines.

I think a pair of CF-34s would be a better option.  The Lycomings on the 146 were about 7,000lb thrust each.  The CFM is in the 20-24,000 class.  A bit overkill maybe?  The CF-34 series on the E170/190 family has a thrust range in the 14,-18,000 range, so you'd be replacing roughly 28k thrust with a modest and reasonable thrust increase of maybe 32k, plus much better fuel consumption, vs giving it 40k+. 

Just a thought.  Plus personal opinion the CFMs just look out of proportion and that much thrust could lead to single-engine handling issues without some other mods. 

Love the idea though!! 
So I got that going for me...which is nice....

During flight trials the CFM turbofans proved troublesome and were replaced with something smaller.
The same engines fitted to the Lockheed S-3A Viking.

TF-34s!   ;D   Military CF34s.  The S-3 engines were early versions putting out about 9k thrust, but the nacelles look great and I'm sure they are containing 14-17k thrust CF34s! 

Looks so much better than that 4-engined thingy they built.

Okay CF34s.
