"I guess if I was going to fly on top of a ceiling in an LSA, I would at least want to make sure I had sufficient training in IFR flight and I had current instrument approach plates on board (electronic) and had made enough practice instrument approaches, I was confident I could make a successful approach."
You have other options. And even if you don't exercise them, the one does not lead to the other nor should it. If you find yourself 'on top' and need to descend as you approach your destination, then yes you will need to penetrate the goo and be on instruments if you stick with your flight plan. But what about turning around once the layer initially thickened to the extent that looks like it might become necessary? It's not like the plane or pilot is stuck on Plan A. And whether you fly with on-board wx or you use Flightwatch/FSS, there should be no reason to find yourself discovering your destination airport is below marginal VFR on arrival.
As mentioned earlier, choosing to fly above an increasingly dense layer (or layers) adds a risk to the flight. Now you're considering a second risk: going into IMC. And then considering flying an approach? The risks just keep piling up...
In my limited current exposure to other pilots and how they fly, I'm amazed at how limited their use of the radio is - whether it's using Flight Following, using Flightwatch or even using the radio on the ground when a taxi conflict arises. I read (here) a lot more discussion about using Flight Following than I hear being discussed among PP's, and that's good to see. But not all the useful data is displayed on your Dynon or iPad, even with ADS-B, nor with the Controller who's working only one slice of airspace. Pireps are one such example. Imagine that layer you're flying over has changed from 'few' to 'scattered', continues to increase, and you have another 1.5 hrs in that direction. Wouldn't a Pirep come in handy? We hear over and over about the negative influence these digital devices have on pilot awareness outside the cockpit. That applies what's available to us from the radio, not just from our eyes.
