I really love how everyone chimed in with their opinions but you are just going for it and doing it. I love seeing this, very cool.
Sergio is also the OG parawinger, his public posts on Peak to Parawing conversions pre-date BRM Maliko by many months.
Sergio gets bonus points for using an inflatable
I think what is being missed is this. Of course you can try it and there are examples quite a few examples of good waterman who can pump a foil up without any device other than their body. What many of us are commenting on is what is needed to do this. An amount of speed to creat lift is the end but how you get there is the question. So you can have a very large foil (2.1 m) like wake thief created for beta foil. All you need is a rock or a runway, or something to launch off of. The other extreme is Gwen, Riggs, Gael, and many others who have achieved flat water pump ups without anything other than pump. These guys all use very long skinny boards with larger foils typically 7 to 8 x 16 to 18 inch boards and 1.5 m and greater foils. In all of these examples pumping is key, size matters, and the only variable is whether you started off a solid object or in the middle of a lake. Just remember while certain products look like magic, you can’t cheat engineering 
Oh and there is are a couple of guys that do paddle up inflatables. Even use smaller foils. Just remember weight (yours vs theirs) can be a difference 5 kg is lot.
