J H Heron modifications

Hello peoples, my first day and first post. I don't know if it is sacrilegious, but I want to really mess with a Heron.
I spent about 10 years in one doing triangles and loops with my dad from about 4 yo, (I'm over 50 now), got bored and went away, played with other toys, but came back to the lightweight heavy hitting versatility of the little Heron. I even feel a little weepy reminiscing of the fun (and pain and suffering) with my now dearly departed dad in our Heron No 7978. I was about 2 1/2 yo when he bought a frame, from memory, and used heavy ply leftover from another man's bigger boat build to clad it. He got kicked out of the 'spare bedroom' with it when my little sister came along, and I "helped" him finish it in the shed, ruining many clothes with glue and paint, to mum's disappointment. Many years later and bored with club racing, and remembering the camping we did in it, I sailed another one exploring alone, dropping in around South Australia's coastline, playing daredevil with shallows and rocks and squalls, having a ball. Messing with alternative rigging, (and peoples minds).

I was researching small boats lately, followed on here the 'best 12foot boat' thread; liked a micro cat with inflatable hulls I saw, that fits into two bags, but stumbled on to the 10 foot round the world race idea, which got me thinking, Uh-Oh. Yes I am a bit crazy too. Micro yacht camping.
A sturdy Jack Holt Heron, (If 7978 is still good I wouldn't mind getting it back), and then: here comes the sacrilege :

Cut off 29 5/16" (745mm) off the stern to get 2.99 m OAL.
widen the sides from the front tank - by 4" at the beam, and by 6"at the transom.
Lower the stern chines by 1" making the hull's stern flatter (a bit).
Move the mast and centreboard forward 10" to keep it near balanced.
Add a 16'bowsprit. And cat style twin rudders. Over engineer the Gunter rig for indestructability, carry the OS jib / genoa, and spinnaker.
I reckon all that might make a 10 foot solid little boat capable of handling almost anything (with a small cabin) if glued and rigged together right.
No other changes needed, unless: reinforce / re-build the centre case and use a steel plate centreboard - a crazy idea I've always had; or widen centre case and fabricate a water filled centreboard like the big TS's.

P.S. A standard Heron jib used as a storm main works very well in squalls. I also have a custom mast head storm main, used hauled up without a gaff.

So what do you all reckon ? Cheap S/H Heron to 10' ocean cruiser ?
Tear it to shreds now before I make it.
