Help me to make decision!

Here it goes.
I have one domain,that is number #1 for keyword with 50k searches,and #5 for 100k searches (same niche,it is just single web page).
To be clear,it is some gaming niche,if it helps.
Now I also have domain,or my main site,with like 20-30 my other niches,that site had been up for more then a year,and it has some authority.
On that main site,I also have same niche,that is number #62 for keyword with 100k searches.
Now,I want to try and redirect,It worked one in the past,but I am not so sure.
I have 2 questions,first: do you think this will help and rank my website better?
Second: If it doesn't rank like I hope,I will lose my earnings,but if I stop redirect,and return my website,will I have problems with getting same position again? Or will google punish me or something like that? Those are my questions. If you didn't understood me,just ask,I will explain further more. Thank you!

And for second keyword where I am #1 on my single website,I am #67 on my main domain.

Explain better in PM

Sent you PM. Waiting for answer

I would just leave it and continue what you are doing with the high traffic site. Why? simply because its a big risk for a small gain, you dont want to bugger your main site. Just keep doing what your doing because it's working (been in #5 for 100k monthly)

Unless its a churn and burn site, in that case go nuts!

It is not churn and burn,but my friend already have #1 for 100k keyword,and he is making 100$ per day. Also for other smaller keywords he is like #5-#10
Also my site is not ranked for all countries,but mostly for USA. (USA hosting,and in webmaster tools,I putted that I target that website).
Question is,if I don't get results that I expect in few days since redirect,and decide to cancel redirect,will I be on same position?

I wouldn't risk it.

Anybody else ?
