blanch after vacuum seal?
Since there's problems vacuum sealing after blanching due to excess water is there a problem sealing the fresh vegetables first and then boiling the package to get the same effect as blanching?

I don't think this will be such a good solution. You can try it, but it probably won't do what you want.
First, there is the problem of temperature control. In blanching, it is critically important that your vegetables heat up quickly, and then cool down just as quickly. If you insulate them with a plastic bag, you are building a thermal delay into the system, and this will reduce the quality of the blanched vegetables. They will be mushier and have worse color than when directly blanched.
The second problem is that you'll still get liquid inside the pouch. Blanching destroys the cell walls of the vegetables. The juices from inside the cells start leaking. And this will happen inside the vacuum bag too. So, you won't have dry vegetables in the bag, you'll have vegetables swimming in their own juice. Unlike the normal blanching scenario, it won't be diluted in water, but it's still probably not what you wanted.
This doesn't mean it's impossible to do it. You can try and see if you like your vegetables better that way. Just make sure that you choose bags which stand up to rapidly boiling water - it may be quite hard finding such bags.

While certain veggies (such as capsicum and green beans) can be sealed fresh, if you intend to freeze your vacuum sealed produce, they need to be blanched first.How do you blanch vegetables for vacuum sealing?
Set aside a separate pot of cold water - 60 degrees or below - for later. Step 2: Bring the water to a boil, then add your desired amount of vegetables. Blanching is an exact science, so consult the NCHFP's chart for specific steam times. Step 3: When the vegetables are done blanching, remove them immediately.Do you have to freeze food after vacuum sealing?
Again, perishable foods must still be refrigerated or frozen for storage after packing in a vacuum or partial vacuum environment. Producing a vacuum means removing air from the contents of a package. Oxygen in environmental air does promote certain reactions in foods which cause deterioration of quality.Can you boil vacuum sealed food?
Yes. You can heat cooked foods, such as leftovers, in a FoodSaver\xae bag. The bags should never be used to cook raw foods.Using the Foodsaver with Blanched Vegetables | Product Demo
