The problem of snow coverage and a large part of the San Gabriels being closed cuts a lot out.
Iron Mt would be my first choice too, except I agree with others, will she like you after that?
It is possible you could hike part of the Desert Divide south of San Jacinto, some of the more southern parts are doable now, though I can't say how good the views are from any of those peaks.
There is also potential in Hines Peak or Santa Paula Peak north of the 126 in Los Padres. I haven't personally done either but I think the elevation gain would be decent.
However my suggestion is one I was going to do two weeks ago but put off: head up Big Tujunga - Angeles Forest Hwy - Upper Tujunga - Angeles Crest to Buckhorn. Take the trail down to Cooper Canyon and follow the Burkhardt trail to Burkhardt saddle. On the way you'll pass by the nice Cooper Canyon falls.
From the saddle, you can head east to ascend Pallet Mt, then drop back down and ascend west to Will Thrall Peak. You can continue west from Will Thrall to the next bump that is benchmarked and is known as the Pleasant View Ridge (well its all the ridge, but that's the marked spot).
This would all be a south facing approach so you would be able to avoid snow pretty well. I think overall you would get 5,000 ft gain out of it.
If you head up for Iron Saturday, I'll be around it maybe I'll run into you guys.
edit to add: also, if Iron is a bit too much, you could hike his little brother Rattlesnake Peak to the west. Similar terrain, but ~ 4000 ft gain instead of 7000).
