This is a very good idea if it works reliably. However, from my experiences with sleeper trains in Sweden (via SJ), it's quite inconsistent.
Just the other month, I took a sleeper from Stockholm to Kiruna and it was delayed by 9+ hours! Good thing this was an unplanned vacation so I had time. The customer service was excellent though, they were attentive and reimbursed me for the train tickets, hotels, food and car rental.
I can't imagine myself using the sleeper trains for any business purposes though as I've had many delays with them.
Yes, I'm all for sleeper trains, but Sweden has the worst maintained infrastructure. They are trying to catch up after decades of neglect, but are open about expecting continuing disturbances for years to come. It is not only a nuisance, reimbursements or not; it's outright risky and a damn shame because we really need trains now
The "new economy" made popular round the turn of the millennium didn't deliver on it's promise of solving everything imaginable, just by turning maintenance of public assets over to lowest bidder private entrepreneurs. Go figure.
