I couldn't wait to get my hands on an ugly hedge along the front of my house when I first moved in (and it had been neglected for a couple of years, so had opportunity to get even uglier than it might have been). But I would suggest that once you have the hedge out, take a look at the space for a little while and see what features on the house you might want to highlight.
I have a couple of purple chaste (vitex) trees here. They typically want to grow as multi-stemmed trees and in this form they spread out, so if you plant a vitex on either side of the front you're probably going to have to train it to be a single-stemmed tree and to keep it trimmed - it sends out new branches from the base all season long. They are beautiful, smell wonderful, grow fast, and are native, but keep in mind how that exuberance may crowd that relatively small space.
It looks like those pines are too deep - we don't see the natural root swell of the trees, we see the shaped pile of mulch around the base. You should gently pull the piled up stuff off of the base of the tree until you can see the butt swell at the bottom of the bole.
You should be able to see the point where the tree gets wider and perhaps the tops of the largest roots. (Don't worry about the fungal threads part of the illustration - I linked to an image simply so you could see the tree root area - let your new trees breathe and see how they look after a while. They add value to your house and property, so don't be hasty about taking even one of them out.)
