Have you considered keeping your Laney and just getting something like a Hot Plate? Although the amp will not sound its best being fully attenuated, you can set it for Load and feed the line out into your interface; then just add an IR for speaker emulation and you are good to go for home jamming/writing.
Almost all of my at-home playing these days is done going DI into my interface with an amp sim; I then strip off the amp sims later and reamp through a conventional mic/speaker setup with an iso cab ... but I can totally understand about not wanting to disturb neighbours, living in an NYC apartment building which is why I have a mess of blankets I wrap around the iso cab, as well as place it on a double isolation platform of Auralex GRAMMA and Black Diamond Racing shelf.
