No, it's not going to be easier.
You cannot get N-400 approved without I-751 approved. And I-751 will likely get denied if you don't get biometrics taken.
What you need to do (my opinion only):
* Attend the address stated in biometrics letter and try to get biometrics done after explaining your situation
* Write a letter to USCIS explaing when and how you tried submitting biometrics and whether you were successul or not
Written communication (certified mail) can be used for later if USCIS asks for proof of you ever contacting them.
Your I-751 can still be saved, at least it's worth trying. Otherwise, if it gets denied, you'll have to file it again, e.g. pay and wait again.
