If you read eugegall's post again you'll see he has no wish to be an airline pilot or instructor so what's the point of encouraging him to do the ATPLs, or even CPL for that matter.
Maybe he just wants to be a PPL/IR.
You can do the 7 IR exams in four months: (I did - some have done it in less) by distance learning with 'brush up ' groundschool days at weekends if you choose the right establishment.................
That's what I and a large number of fellow PPLs have done over the last 10 months.
Can't comment on the twin versus single notion and as eugegalls seems 'comfortable' then the significant extra expense of an IR in a twin won't be a problem.
I don't propose to get embroiled in the 'do the IMC, you won't regret it' or the 'go to USA and do the FAA/IR' arguments they've been done to death elsewhere.
