Yes Younggun, that will work. I started off with a piece like that, which only covered the front half.

If your hair at the crown is thinning, you will need to go for a fairly low density for your piece, so that the two match.

Skin bases are very convenient and give a strong hold, but in my experience they arent quite undetectable enough to allow you to expose your hairline. I would suggest you order the piece with downward scalp-hugging ventilation, and then crop it fairly short into a slight fringe (a la Kevin Costner In The Bodyguard or Steve McQueen). That would work really well, and be very low maintenance.
