Rain Water Downpipe and Floplast Bottle Gully Connect Drainage and wastage systems and plumbing help, advice and answers

[KingShaves]

Hi there. I'm after some advice on how I could improve the drainage (see the image attached). It's more about the finished look than anything else. Pebbles/stones will fill the gap between the house and paving at some point. I have two drains, the downpipes collect rainwater, both drain covers are below surface level therefore not for surface water. Can I somehow run the downpipes lower and buy some sort of connector - connect downpipe to the floplast bottle gully directly?
