Has he been crated trained at all yet? If so, you could put his crate beside the dog bed or on your side of the bed, if there's room. When I get new puppies, they sleep in their crate but it's right beside me on my side of the bed so if they whimper or whine, I can reach down and let them know I'm right there.
Our first lab was a bit aloof when it came to snuggling when we got a new puppy when he was about 6 years old. Lark learned that she'd be OK not sleeping right up against him- like Marcie, Chase would just get up and move. Of course, he'd go sleep in another room from where we were sitting even before we got the puppy. My current 2 don't sleep touching each other during the day, but they are usually within a couple of feet of each other. The younger one (10 months old) has slept over night in a crate since we got him.
As a side project, have you taken Linus to any classes or does he do any activities without Marcie being along? I'm just wondering if it would be beneficial to him to get some more experience doing things independently- obedience classes, nose work, rally or something that might make him feel more confident just by himself. Not that Marcie is old or sick, but should something devastating happen to her, it might be good if he felt more confident in general, if you think maybe he doesn't.
