If you have one night at Skoki Lodge, here's an itinerary I'd recommend: hike in (and out) via Packers Pass instead of Deception Pass, unless the weather is terrible. From the pass, walk up Packers Peak if the weather is good. After arriving at the lodge, hike up Skoki Mtn. if you like. Next day, hike up to Lake Merlin and go as far above the lake on the trail to the head of Merlin Valley as you can, bearing in mind you have to return to the Skoki trailhead (at the top of the access road, about 3-4 hrs. from the lodge). Even if you have to walk the road to the parking lot (I think the lodge van leaves at 3), it's only an hour and well worth it if you can spend extra time hiking.
If you have one night at Mosquito Creek camp, Mo5, or the car camp at the trailhead, next day I'd hike up to Molar Pass rather than N. Molar Pass, or hike up to Mosquito Lake on the N Molar trail, then go cross country over to Molar Pass.
Eiffel and Cirque are day trips if you have front country accommodations; some people do Cirque as a day trip from Calgary. Eiffel is a moderate scramble with relatively few visitors (once you leave Larch Valley), while Cirque is seldom more than steep hiking with busloads of visitors. I'm sure they both would be highly recommended by anyone who's done them.
Another possibility is to stay at the campsite a short distance up Healy Creek and next day hike to Simpson Pass, Eohippus Lake, Monarch Ramparts and Healy Pass.
