Hello,
For the last ten years, I've had a pair of B&W 683. The affection value is high, so upgrading them is very tempting.
I want to completely remove the existing tweeters and make a new front panel to remove the hole. I want to buy tweeters from B&W 700 series, and put them on top of the speakers. Additionally, the woofers must be replaced due to dents, considering B&W 603 woofers.
The FST mid-range both sounds and looks good, in my opinion. So they stay.
Is it possible? Reckon new crossovers are needed as well. Does anyone here know of one that can do the job, maybe adding a DSP? Or must I build one from scratch?
I am new to this, so please feel free to share your knowledge.

Anything is possible if you know how. I would first investigate why the HF response is so bumpy. Original single cap and one padding resistor acting as tweeter HP filter leaves options for improvement. Tweeter itself may not be a problem at all.
I don't understand. You say affection value, and then you want to make a franken-speaker, with different tweeter and woofers and a new baffle. If you like the speakers, enjoy it as-is or buy new 683 woofers if the dents affect the sound. If you don't like them anymore sell them as-is and buy or build something new.
Changing tweeter and woofers will need an updated crossover, but without measurement equipment you are essentially shooting in the dark. Simply judjing from the published crossover, there could the possibility to improve the crossover maintaining the existing drivers, in particular the mid-tweeter crossover point and slopes. But again without measurement equipment (and experience, I'd say) this is simply not possible.
Another thing to take into consideration: the 6xx is the B&W low-cost series, and their cabinets aren't state-of-the-art. I wouldn't use such a non optimal cab to improve simply on drivers.

So, the tweeters and the woofers (that are scratched) are not liked anymore but you have nostalgia for the looking of the object or some subjective emotional souvenirs?
Like a car sometimes it is time to give it up and pass to the next one. On this one you risk to spend more monney than you think for a bad average result if the goal of a loudspeaker is still about reproducing music.
Change one or several drivers then the filter needs to be designed again. Coils are expensive like a setuping. Spending monney but if a hobby doesn't worth the time and cost with counsumer loudspeakers.
A brandnew cheaper loudspeaker of nowadays will sound better imho. If you re very nostalgic you will need to find the same woofer and change the electrolythic capacitors. Because of their aging it beginns to sound worse after 10/15 years and it is not the same sounding loudspeaker after 20 years because of those electrolythic caps.
A recent second hand of a near model would make sense despite you highligthed your attachement.

Any action other than buying new speakers requires a microphone first.
So if you want to do anything yourself, then your very first step is to buy a microphone.
I would advise UMIK-1 and the REW program. And learn to measure by the example of yours B&W 683. Watch video on youtube.
