How to deal with "illiberal" corruption?

Two issues keep the debate around the new Multiannual Financial Framework (MFF) going: one is about how to find a mechanism to react to governments which do not comply with the Copenhagen Criteria, i.e. infringe democratic and/or rule of law principles (the infringement of democratic principles is more indirect as the sheer outcome of elections favours the governments of Hungary and Poland - although in Poland the tide may turn - but the circumstances under which these governments win the votes are at least dubious) without resorting to the famous (or rather notorious) Article 7, which is rightly called the "nuclear option" as it is very strong and virtually impossible to implement. It has to be noted also that this "nuclear option" is not directly so nuclear as it strips a country from its voting rights but leaves all other right untouched - of course after this the other member states can vote other sanctions if they are in line with general law.
The other question is also raised in the context of the projects in Hungary where the government is distributing EU funds with an extreme speed - leading to suboptimal decisions in itself - and favours its cronies in this distribution.
As it seems that - at least in Hungary - these two negative phenomena go hand in hand - and the concentration of power and hollowing out of all checks and balances really ensures that cronyism and corruption cannot be brought to court or hindered any other way, including wide publicity, the two questions are mixed together.
Proposals are tabled which would make EU funds conditional on rule of law criteria. In terms of proper use and avoidance of fraud, joining the European Prosecutor's Office is favoured. On the other hand, soon a new Financial Regulation will be voted which will simplify the disbursement of EU funds.
EU structural funds are an important source of economic development, a positive factor in the image of the EU and also help cohesion between the countries (also by enabling that their economic development approaches them to each-other - they are also called cohesion funds). I totally agree with Markko Markkula, president of the (European) Committee of the Regions, who emphasised the importance of these funds in an interview already serving as a preparation to the fight around the new MFF, arguing that the cohesion funds should not be cut. A recent article (and one of a leading Hungarian commentator who can also not be suspected of being on the side of the present Hungarian government, arguing that austerity will not break the government of Orbán) warns that the cut of funds can be counterproductive.
So what?
My proposition is that the decisions (including acceptance of projects and procurement) should be more centralised and also more controls should be applied, covering the cost of these from the funds made available to the country in question. These controls should also depend on whether the coutry joins the European Prosecutors' Office.
This would of course require additional resources which is always difficult to achieve but even more difficult now when EU sources are decreasing due to the Brexit. Therefore the structural funds should be used for this purpose. This would not be such a sensitive cut as what is proposed in the framework of the new "conditionality" proposals. Also, joining the European Prosecutor's Office should be the precondition of applying the simplifications in the new Financial Regulation.
