almost yes... though the lines touched each other, your formation has too many and too big gaps...

I use the quincunx formation with some succes though, it did always result in the slaughter of many skirmishers but when my hastati punched in, they usually got the job done.

But you need to mod a few things to get a proper legion.

1st, mod all roman premarian (camillan and polybian) infantry units to a 240 on huge, which is 60 on default.
2nd, change the attack value of your skirmishers darts to a higher one, 8 or something like that.

This way your legion would have around 4500 men which is the closest you can get to the real number of a roman legion. Conquer a part of the meditaeranian and you can field 4 of the legions, they will make a formidable force. The make up would be something like this: 1 general, 1 equites romani, 4 veles, 5 hastatii, 5 principes, 2 triarii, 1 accensii and 1 rorrarii.
