LMoP and DoIP as a West Marches campaign

With how life changes over time, I want to change the way I play my (once) current D&D campaign. Back in 2023, my then 8th grade daughter finished watching the 4th season of Stranger Things and asked me to teach her and some of her classmates how to play D&D. I hadn't played since the early 1990's (AD&D) so I purchased a STARTER SET and ESSENTIALS KIT to set off learning (for myself) the new 5e version. I liked it, a LOT!

We started our "D&D Club" and had several months of playing every 2 to 3 weeks with a party of 6 learning the rules, gameplay and playing the first chapter of LMoP (only completed Cragmaw Hideout and then getting to Phandalin). It was slow-going, with a party (that large) of newbies and a rusty DM, but it was some of the most fun I've had with a younger group. As the kids got older, they had less free time on their hands and, over the last two years, we have played very infrequently.

Now they are in 11th grade and occasionally talk of jumping back in. Sports and Jobs have made scheduling more than a challenge. I found that 'Player-Driven' campaigns like a West Marches Style game can be fun. Those who are interested would plan to play an adventure with a base of operations to return to. I thought of Phandalin and the two boxed sets that take place in and around there.

What do you think of running Lost Mine; Dragon of Icespire Peak; and Shattered Obelisk as a West Marches / Player-Driven campaign? It could develop as objectives are accomplished in any of the modules and the player characters could advance when they play. Others may join in or resume, as time and interest manifest. It keeps the world open without having to coordinate everyone and it allows the scenarios to play out. We would open a Discord server to communicate, track all the progress, provide quests/opportunities/rumors/etc. so the interested groups could pick something, schedule with me (or another DM) and log their exploits.

Just curious if this subreddit thinks this a good choice to follow or if there is too much to retool in order to have a good experience. I realize that in most West Marches, it is a dynamically growing (or homebrew) world, but I really enjoy the Phandalin setting and the stories attached from those published adventures. I'm very open to suggestions.

Thanks in Advance!
