A good repair person can have the guitar repaired so that it would sound very close to what it was oriiginally. A great repair person can not only do that, but make almost all of the damage visually disappear. The guitar is finished in nitro lacquer, so as long as the cracks are repaired properly, and tightly, it is only a matter of matching the new lacquer to the existing lacquer. The new lacquer will "melt into" the existing lacquer without leaving any marks, which is a real advantage to lacquer.
The tail block would need to be carefully inspected, and if cracked, and depending on how extensively it is cracked, it may be possible to glue it back together, or it may be necessary to replace it (stay away from that if possible). The tail block would need to be inspected and fixed before the soundboard is glued back down. The center seam split is common, and the side repairs may or may not be made more complicated by the state of the tailblock, but side cracks are not difficult repairs in general.
Depending on the skills of the person doing the repairs, this is very doable. Get the best person you can to do the repairs' DV-72s are rare, and very worthy of good repair work.
